Ballistic apps

What's a good all round ballistic calculator app to use

I find ballistic AE pretty good

I use shooter. Strelok is another you hear people using.

I use Strelok Pro, its pretty good for what I do once you have sorted all the data entry

Strelok pro is a good one.Bullet flight m is another

I find Shooter and Applied Ballistics give almost identical results, I use them side by side. As with all these apps its all about what you put in that determines how accurate they are. If you stuff up any of the inputs such as atmospheric pressure. bc or muzzle velocity they will give you rubbish firing solutions. It's taken me a couple of years going around in circles to start to understand how to populate them and get sensible results. What ever app you run you will need a device such as a Kestrel to give you atmospheric conditions and wind speeds and a laser range finder.

It's what you do with it...

As Dermastor says the main work is getting good data to input. I use shooter and it's pretty user friendly but its default is imperial and you need to go back and double check the units after you've set it up. Virtual bullets dont fly so well in 1013 inches of mercury.

Second, test on paper somewhere past the farthest you plan to shoot. Adjust velocity to match your measured trajectory and use the actual air pressure at the time you shot (500 or 1000m above sea level makes a lot of difference shooting at a range of 500m). Most phones have a barometer so download an app to read it out.

Finally, print out a representative drop card and tape to the stock because often it's too bright on the hill to read your phone or not enough time.
